Control[1]
The input device you use will depend on the requirement.
Analog and Digital[edit]
Sensor types[edit]
Please read this article for a pretty good example of different input devices
The following are some sensors with explanation and example uses:
- Heat: measures temperature, e.g. central heating, fire alarm
- Humidity: measures water vapour in the air, e.g. greenhouses, swimming pool halls
- Infra-red: measures radiation, e.g. security alarm systems
- Light: brightness, e.g. security lights
- pH: acidity levels, e.g. environmental monitoring
- Pressure: force applied on the sensor, e.g. automatic doors, alarm systems
- Smoke: particles in the air, e.g. fire alarm
- Sound: sound pressure level, e.g. noise pollution monitoring, voice controlled systems, alarm systems
- Tilt: angle of tilt, e.g. aircrafts, alarm systems installed in windows
- Touch: more sensitive than pressure/detects contact, e.g. robots
Standards[edit]
- Evaluate different input devices for the collection of data in specified situations.
